Methods Dental fluorosis of children aging 8～12 years in each of the experimental spot was examined. Drinking water, brick tea water, milk tea water, urine and so on in each of the experimental spot and the content of fluoride was measured with F-ion selective electrode method. Results Two hundred and twenty-six dental fluorosis of varing degree were found among 332 children examined with a rate 68.07%. Twenty-three portions of water sample, 84 mild tea, 181 child's urine, and 113 adut's urine were collected, and their averaged level of fluoride was 2.57, 3.82, 3.85, and 5.10 mg/L, respectively. In 203 adults clinically examined, 131 present positive fluorosis signs and symptoms with a positive rate of 64.5%. In 188 examined by radiographs, 73 people were diagnosed as bone fluorosis, the detectable rate was 38.8%.
